Solar in Gilbert
Gilbert has transformed from a small agricultural town to one of Arizona's largest and fastest-growing communities. With many newer homes built in the last 20 years, Gilbert is well-suited for solar—though SRP's demand-based rate structure requires thoughtful system design.
Gilbert Solar Advantage
Gilbert's newer housing stock means many homes have modern electrical panels and solar-ready roofs. Combined with 6.0 peak sun hours, Gilbert offers excellent production potential—the key is managing SRP demand charges. (Source: NREL Solar Resource Data)

Cost Per Watt
- Gilbert average: $2.40-2.80 per watt
- Budget installs: $2.20-2.40 per watt
- Premium installs: $2.80-3.50 per watt
Payback Period
Gilbert's family homes often have higher usage, improving solar economics:
- Typical payback: 11-14 years
- With battery storage: 10-13 years (better demand management)
- 25-year savings: $25,000-45,000+ depending on usage
SRP Policies & Demand Charges
Salt River Project serves Gilbert with demand-based rate structures. Understanding these is essential for solar planning.
SRP Demand Charges Explained
- What they are: Monthly charges based on your peak hour of usage
- Peak measurement: Typically during afternoon hours
- Solar challenge: Clouds passing during peak can spike demand
- Family impact: Multiple AC zones can create high peaks
Gilbert Family Homes
Gilbert's family-oriented community means larger homes with more AC zones and higher usage. While this creates higher bills to offset, it also means higher potential demand charges. Battery storage helps manage peak usage. (Source: manufacturer specifications and EnergySage data)
Rate Options for Gilbert
| Plan Type | Demand Charges | Recommendation |
|---|---|---|
| Customer Generation | Yes | Consider battery |
| Time-of-Use | Varies | Shift loads wisely |
Demand Management Strategies
- Battery storage: Cover demand spikes when solar dips
- Smart thermostats: Pre-cool before peak hours
- Pool pump timing: Run during solar production
- EV charging: Charge overnight or during solar hours
Arizona Incentives
Available Incentives
- Arizona Residential Solar Tax Credit: 25% of cost, max $1,000
- Property tax exemption: 100% of solar value excluded
- Sales tax exemption: On solar equipment
- SRP programs: Check current battery incentives
Federal Options
- Purchased systems: No federal credit (25D ended 2025)

Gilbert Considerations
Newer Home Advantages
- Modern panels: 200A service common, solar-ready
- Roof condition: Newer roofs ideal for solar
- Building codes: Many homes wired for solar
- Minimal upgrades: Lower installation complexity
Gilbert-Specific Factors
- HOAs: Common but Arizona law protects solar rights
- Master-planned communities: Consistent roof orientations
- Growing families: Usage tends to increase over time
- EV adoption: Growing, adds to solar value proposition
Production Estimates
- Annual production: 1,700-1,900 kWh per kW installed
- 8 kW system: ~13,500-15,000 kWh/year
- Best months: April-June
- Winter production: 50-60% of peak
Gilbert Production
An 8 kW system in Gilbert produces 13,500-15,000 kWh annually. For a typical Gilbert family home using 12,000-18,000 kWh/year, solar can offset 75-100%+ of electricity usage. (Source: EPA Greenhouse Gas Calculator)
The Bottom Line
Gilbert is well-suited for solar with proper planning. Newer homes, excellent sunshine, and family-level usage create good economics. SRP demand charges require attention—battery storage often helps.
Key points:
- 6.0 peak sun hours—exceptional production potential
- Newer homes often need minimal electrical upgrades
- Higher family usage improves solar economics
- SRP demand charges require battery or load management
- 11-14 year payback typical, 10-13 with optimization
